The Current State,Challenges,and Strategies of Salt-Alkali Agriculture in the Yellow River Delta Using VOSviewer for Visualization Analysis
The Yellow River Delta boasts superior geographical location and abundant agricultural resources,of-fering unparalleled conditions for agricultural development.Utilizing the CNKI Core Collection Database,an ad-vanced search was conducted using the keywords"the Yellow River Delta"and"agriculture",selecting 1333 publications from between 1987 and 2022.The three clusters of keywords"saline-alkali land","crops",and"water resources"were revealed by using VOSviewer visualization software.Further visualization analysis of these three clusters was performed.The analysis of annual publication volumes and research hotspot maps sum-marized the current state and key directions of research on saline agriculture in the Yellow River Delta in re-cent years.Additionally,in response to the challenges of high difficulty in utilizing saline-alkali land,a monot-onous crop planting structure,and prominent water resource conflicts facing the development of saline agricul-ture in the Yellow River Delta,specific countermeasures were proposed from the perspectives of soil improve-ment,optimization of planting structure,water resource adaptation and water-saving technologies,and ecological synergy enhancement.This study provides reference for issues related to the development of saline agriculture in the Yellow River Delta region.
